How would I find the derivative of a unit step function? I understand that the unit impulse function will be used but I'm not sure how to use it.
I am trying to find the derivative of this:
$v(t) = u(t+1) - 2u(t) + u(t-1)$
$u(t) = 0$ when $t < 0$
$u(t) = 1$ when $t > 0$
The relationship between unit step function and impulse function:
δ(n) = u(n) - u(n-1)
$ δ(t)=du(t)/dt $
